This is the default implementation of
OEConfTestBase. It never combines connection tables
into multi-conformer molecules. This function is set as the
conformer test to use by all of the oemolistream
constructors.

Always returns false for this object to indicate that the
implementation of the
OEConfTestBase::CompareMols method is
“trivial” and always returns false, indicating molecule
copying can be elided in OEReadMolecule.
